Retrieving IMEI, IMSI, Network Info (Cell Id, Location Code) 3rd Edition.

In the 2nd edition there are many ways to retrieve the IMEI and IMSI. The one popularly used is the 3rd party “MobInfo Dll”. In Series 60 3rd edition there is no such third party Dll. Instead “CTelephony” needs to be used.

I’ve seen lots of threads for 2nd edition, but did not get good pointers for retrieving these parameters for 3rd edition.

Following is my contribution on how to retrieve IMEI and IMSI. Along with that you can also use this code to retrieve network info (Cell Id, Location code) It can further be extended to retrieve other network info.

Note: This piece of code requires "ReadDeviceData" Capability.

You can further extend the above code for retrieving other network information.
